Abstract
A three-dimensional printing kit can include a polymer build material and a fusing agent. The polymer build material can include from about 80 wt % to about 100 wt % polymeric particles. The fusing agent can include an aqueous liquid vehicle, an electromagnetic radiation absorber to absorb radiation energy and convert the radiation energy to heat, and an endothermic decomposition compound that can undergo thermal decomposition at a temperature ranging from about 60° C. to about 400° C.
Claims15
A three-dimensional printing kit comprising:
- a polymer build material including from about 80 wt % to 100 wt % polymeric particles;
- and
- a fusing agent including:
- an aqueous liquid vehicle,
- an electromagnetic radiation absorber to absorb radiation energy and convert the radiation energy to heat, and
- an endothermic decomposition compound that undergoes thermal decomposition at a temperature ranging from about 60° C. to about 400° C.
A method of three-dimensional printing comprising:
- iteratively applying a polymer build material as individual layers to a powder bed, wherein the polymer build material includes from about 80 wt % to 100 wt % polymeric particles;
- based on a three-dimensional object model, selectively applying a fusing agent onto individual layers of the polymer build material, the fusing agent including:
- an aqueous liquid vehicle,
- an electromagnetic radiation absorber that absorbs radiation energy, and
- an endothermic compound that undergoes thermal decomposition at a temperature ranging from about 60° C. to about 400° C.;
- and
- exposing the powder bed to electromagnetic energy to selectively heat and fuse portions of individual layers of the polymer build material together in contact with the fusing agent to form a three dimensional object, wherein the endothermic decomposition compound causes a structural modification of the three-dimensional object in response to the heat.
A system for three-dimensional printing comprising;
- a polymer build material including from about 80 wt % to 100 wt % polymeric particles;
- a printhead fluidly coupled to or fluidly coupleable to the fusing agent to selectively and iteratively eject a fusing agent onto successive placed individual layers of the build material, the fusing agent including an aqueous liquid vehicle, an electromagnetic radiation absorber to absorb radiation energy and convert the radiation energy to heat, and an endothermic decomposition compound that undergoes thermal decomposition at a temperature ranging from about 60° C. to about 400° C.;
- and
- an electromagnetic energy source positioned or positionable to expose the individual layers of the build material to radiation energy to selectively fuse the polymeric particles in contact with the electromagnetic radiation absorber to iteratively form a three-dimensional object and cause a structural modification of the three-dimensional object in response to the heat due to the presence of the endothermic decomposition compound.
